CGminer v3.8.5 on Broadcom based DD-WRT / OpenWRT

[OtaconEmmerich]

ARGH! This is the 5th time or so I've gotten a Seg fault or LibUSB I/O error.  It seems to happen almost every 24-30 hours or so. I wonder if this is an issue in 3.6.1? I hope updating to 3.6.3 fixes it, I was waiting for another update but..Maybe I can make a scheduled script to restart it every 20 hours if it still shows up..What would be the best way to do that?

Cron can do that, you'll have to google it though.

Try 3.6.3, may work better. I'm not going to release 3.6.4, the changes I don't think will much affect this build.

Is there a way to get cgminer working on Atheros based router (TPLINK WR1043ND) that cannot use 'service' command.

Got DD-WRT installed with Optware (Optware trick for Atheros comes from http://www.dd-wrt.com/phpBB2/viewtopic.php?t=86912&postdays=0&postorder=asc&start=0 that permit to use 'opkg' instead of 'service' command).

Tried with 'opkg' :

Code:

root@BNT /tmp $ opkg install cgminer_3.6.3_mipsel.ipk 
Unknown package 'cgminer'.
Collected errors:
 * pkg_hash_fetch_best_installation_candidate: Packages for cgminer found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package cgminer.

ipkg returns nothing :

Code:

root@BNT /tmp $ ipkg install cgminer_3.6.3_mipsel.ipk 
ERROR: File not found: //usr/local/lib/ipkg/lists/whiterussian
       You probably want to run `ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/non-free
       You probably want to run `ipkg update'

       You probably want to run `ipkg update'
/bin/ipkg: line 1184: sort: not found
root@BNT /tmp $ 

The error returned with ipkg comes from the optware atheros trick and doesn't matter.

Thanks for help.

There's your problem.

If I put a lot of effort in, I probably could get it to compile for atheros... but then I couldn't test it in any way.

[3KyNoX]

Thanks for your reply.

I could test it, and help you in any ways. I'm compiling things since a long time using gcc on linux, but can't find your method for cgminer.

Anyway it could add support for Atheros peoples. I'm ready for testing purpose.

Yet another Seg fault 
How can I check to see what's causing these? At least this time around I didn't have to reboot the router.

I've tried to make the current git master compile against the system libusb optionally now with the --with-system-libusb option.

[P_Shep]

Mine's been up for over 6 days now with no issue.

I could compile a debug version for you, which you'll have to run with gdb, to try can catch the error.

There's a 'low memory' flag you could try adding to cgminer.sh '--lowmem' might help?

Nice, that's very useful, thanks.

I'll try running with that flag next time, I can't get cgminer running as a service FYI. Every time It crashes I have to kill the screen instance if it doesn't default back to a prompt and retype the whole damned line. I wouldn't mind running a debug verison if it will help figure out what is causing this bug.

how to add patch for HEX16A in cgminer for openwrt from this post

The patch for cgminer is available for download from the technobit's web page link

Ask Con. This isn't the place for that.

Upped to 3.7.2

[OtaconEmmerich]

Had an error installing the new update.

Code:

Upgrading cgminer on /opt/ from 3.6.3 to 3.7.2...
sh: /opt/ipkg-rIrXPj/cgminer-d2hl3D/preinst: not found

Upped to 3.8.1

I've left off the pre/post inst scripts so it works on asuswrt.

[OtaconEmmerich]

Spits out a bunch of errors out for me.

Code:

[2013-11-17 23:00:38] AMU 0 SendWork usb write err:(-12) LIBUSB_ERROR_NOT_SUPPORTED

along with this after it finishes spitting out the errors.

Upped to 3.8.3:

https://www.dropbox.com/s/j5zxk6bwovp7t50/cgminer_3.8.3_mipsel.ipk

Another 'Rpi only' device was added in the last version which I shouldn't have enabled. Removed that now. Can't say if there's be no AMU errors though.

[OtaconEmmerich]

Boo 
Same error as last time. LIBUSB_ERROR_NOT_SUPPORTED 
Back to 3.6.1 again.

[P_Shep]

Yeah, seems 3.6.3 is the last one which works. It's the one I've left running since I haven't had any problems and needed to upgrade.
